rest as my user.... almost exactly identical to your machines setup. id 0 is root and id 1000 is user with NO powers, everything inbetween is a sliding scale, and users are attached to numbers so 102 would be ok with no user associated with it. 101 is pretty high up

look for your self

cat /etc/group

(i think theres a file that does this for users but its escaping me for the moment)
